Reel duplication of the whole or of
any part of this film is prohibited
In lieu of transcripts, however
enlarged photocopies of selected

may be made in order to facilitate
research.

A Note on the Sources

The pages which were microfilmed for this collection are
in generally good condition in the original. There are
some pages, however, which due to age are lighter than
normal. Additionally, because some volumes are very
large and have been bound tightly and cannot be un¬
bound, there are intermittent occurrences of slight dis¬
tortion of the edges of a small percentage of the pages.
We have made every technical effort to ensure complete
legibility of each and every page.

A Note on the Sources

The pages which were microfilmed for this collection are
in generally good condition in the original There are
some pages, however, which due to age are lighter than
normal. Additionally, because some volumes are very
large and have been bound tightly and cannot be un¬
bound, there are intermittent occurrences of slight dis-
tortion of the edges of a small percentage of the pages.
We have made every technical effort to ensure complete •
legibility of each and every page.
